pyDEA (https://github.com/araith/pyDEA) is one of the main open-source software for running data envelopment analysis (DEA) in Python. It was designed to run through a graphical user interface or through the command line interface. Running pyDEA with Python scripts is not very trivial as you will need to dig into the package and find the methods you want.
pyDEA wrapper provides a wrapper approach to use pyDEA in Python scripts. It defines a Python object with methods that call pyDEA to solve DEA problems and provides some useful functions for post-solution analysis.
Install pyDEA and put pyDEA_wrapper.py in the working directory of your DEA project.
Usage illustrated in pyDEA_wrapper_usage.py.
